Problems solved by technology

[0003] CN 105780540 A discloses a foaming anti-slip printing for textiles. The patent uses foaming pulp, acrylic resin, and a crosslinking agent. The linking agent improves the washing fastness, but the content of foaming agent decreases after adding acrylic resin to the foaming slurry, and the foaming height decreases; adding a cross-linking agent at the same time affects the operating time

Abstract

The invention provides an environment-friendly special high-temperature foaming paste for printing and dyeing and a preparation method thereof. The composition of the foaming paste includes a special acrylic emulsion for high-temperature foaming, titanium dioxide, a thickener and a defoamer. The foaming paste is easy to operate during the printing process, the printing is not sticky, foams at high temperature (above 180°C), has a good three-dimensional effect after steaming and washing, has a smooth surface, does not collapse, and does not change yellow. Textiles have excellent washing resistance, which greatly enriches dye printing.

Description

technical field [0001] The invention belongs to the field of printing and dyeing materials, and relates to a foaming pulp, in particular to an environment-friendly high-temperature foaming pulp special for printing and dyeing and a preparation method thereof. Background technique [0002] At present, dye printing still plays an important role in daily life, and pigment printing cannot replace dye printing for the time being, because dye printing has the characteristics of bright colors and soft hand feeling. However, the conventional bright colors on fabrics can no longer meet the aesthetic requirements of modern people, and the three-dimensional effect with brightly colored prints is more attractive to consumers. The three-dimensional foaming slurry specially used for printing and dyeing needs to be steamed and washed, that is, the problems to be solved are: high temperature foaming without yellowing or collapse, and good washing fastness. [0003] CN 105780540 A discloses...
